Answer:
A. 8
Step-by-step explanation:
BE = ½(CD) (midsegment theorem)
BE = 2x - 10
CD = 12
Plug in the values
2x - 10 = ½(12)
2x - 10 = 6
Add 10 to both sides
2x - 10 + 10 = 6 + 10 (addition property of equality)
2x = 16 (addition property of equality)
Divide both sides by 2
2x/2 = 16/2
x = 8 (division property of equality)
